Recommended procedure
1.
Start the system; see page 32.
Start the HPS.
2. Unclamp and clamp the crosshead lock cylinders. They should operate smoothly and quickly with no
unusual noise. The Interlock status in the controlling software should indicate
Normal
when the
crosshead is clamped.
3. Loosen the crosshead support collars so that they can slide along the columns (use hex-bit socket
and ratchet wrench). Allow them to rest on the top of the guide plate or on the lift cylinder support
brackets (depending on frame model).
4. Unclamp the crosshead lock cylinders and operate the crosshead lift cylinders to move the crosshead
through its full range of motion. It should move smoothly with no unusual noise or erratic motion.
5. Return the crosshead to the desired operating position.
6. Clamp the crosshead lock cylinders.
7. Adjust the crosshead support collars on the columns so that they are in contact with the bottom of
the crosshead (use hex-bit socket and ratchet wrench). Secure the crosshead support collars to the
columns. Tighten the cap screws to the torque specified in
(use hex-bit socket
and torque wrench).
8. If you notice any problems resulting from this inspection, contact your local Instron Services
department as directed on page
Clean the columns
It is necessary to clean the columns at the frequency stated in the
. The cleanliness of the columns will affect:
•
How well the crosshead is clamped by the crosshead lock cylinders. Dirt and oil could allow the
crosshead to slip.
•
The life span of the wipers that are used in the guide plate. These wipers scrape away any dirt or
debris that is on the columns and will deteriorate more quickly if the columns are not kept clean.
In most cases, it is sufficient to clean the columns with a petroleum-based solvent or cleaner to remove
dirt and oil. If necessary, use steel wool or a ScotchBrite
TM
pad to remove heavy dirt or oil. Wipe the
columns dry; any residue on the columns could prevent proper clamping of the crosshead. Do not apply
any lubricant to the columns.
All equipment must be supplied by the customer unless noted as “supplied”. For a list of equipment that
was supplied with the system, refer to
